Hello.
I have an old 4.2 V8 without any service history, so to be sure I'm doing full timing belt change + water pump, oil and filters. I have also heard you should change an o-ring and a pipe on the oil cooler at the same time. Does anyone have a parts number for this? And the timing belt, is it 077109119? B, D or E? I see there are some belts with 253 teeth, and some with 299. Is the shorter ones for cars without A/C? Are there any special tools, except the VAG 3341 cam holders I already got, I absolutely need? Thanks in advance.

The timing belt does not drive the A/C pump. The AC pump is driven by the serpentine accessory belt. Whilst replacing the Cam timing belt, you would do well to replace the idler pulleys, the tensioner, the OEM thermostat and water pump. What year car? There is a 32 valve and a 40 valve engine with a split in 2000. Usually .the better suppliers specify a VIN number split. EDIT.. You mentioned having a 95 & 96. They weren't sold in the U.S. until...? 1997? Anyway, your engine is a 32 valve and your timing belt kit would look something like this: https://www.fcpeuro.com/products/aud...ro-audia8tbkit
The tell-tale is your tensioner looks like a small shock absorber. The later kits have a different tensioner design.
